Synthesis of Hexamethylenetetramine Dinitrate (HDN)

In a beaker 26 g of hexamine is dissolved in 60 mL of very hot water and cooled down to 0°C, the beaker is then immersed in an ice bath. An addition of 79 g of  60% cold nitric acid is started with stirring while the temperature is maintained below 10°C. After the addition is complete the solution is stirred for additional 5 minutes, the mixture is filtered, washed with 200 mL of ethanol and dried in a desiccator. The pure HDN is hygroscopic so it may be stored with and drying agent pad.
